I'm currently (pain-stakingly) trying to do what should be a simple task of upgrading a number of 7945's on a UC520.
CCA is 3.3.2 and the UC520 on 8.6.
The 7945's are on 8.3.2, Im trying to go to 8.5.2.
Any attempt to drag and drop results in the cursor icon symbolising the drag/drop feature (of any type) is not supported.
So to confirm no errors, no CCA prompts or notifications of any type, just what looks like a windows icon suggesting its not possible.
TFTP server is operational as I can upload software packs etc. and download configs.
Am I missing something, surely this should be a simple task...?
Any help would be very much appreciated.
Please review the follow document to verify connection requirements:
What is the file you are uploading? It should be a ZIP file.
Is there a reason you don't want to upgrade to 9.1.1 which is included in the software pack?
Nevermind, I doublechecked the release notes from 9.1.1SR1 which states:
For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to version 8.5(2)SR1 or greater, you must first upgrade your firmware to version 8.5(2). Once you have upgraded to version 8.5(2), you can upgrade your IP Phone to version 9.1(1)SR1 or later.
This has never worked properly for us, and there is no way on earth we are leaving UAC disabled on a windows box that is connected to the internet.
